2、ere do you think you are? 你認(rèn)為你現(xiàn)在是在哪兒, do you think 是用在特殊疑問句中的插入語,用來征詢見解或表達(dá)看法。因為句中插入語已經(jīng)是疑問式,主謂倒裝了,所以you are的位置不能再對調(diào)了。插入語一般是對句子加一些附加的解釋,在句子中作獨(dú)立成分。常用來作插入語的結(jié)構(gòu)有I hope, I think, Im afraid, you know等。插入語可以位于句尾或句中,有時也可出現(xiàn)在疑問句中。Where do you think you are?

3、 race track. 否定句要在前面否定:I dont think we are on a race track. 像這種推測類的動詞,如think、sure等,要在主句上否定,如:I dont sure this thing is true.2. You must have been driving at seventy miles an hour.

4、ng when I called you last night. 昨天晚上我給你打電話的時候，你肯定在喝酒。這種結(jié)構(gòu)用來表示對過去正進(jìn)行的事情的推測。下文中的cant have been是 cant have been driving的省略式,在意思上與must have been driving正相反。cant（must表猜測的否定形式）must+動詞原形 eg: You must be sick. 你一定是病了。must+be+v-ing eg They must be drinking now。 他們一定在喝酒。must+have+過去分詞 表示對過去動作的猜測。 You must ha
